How much boost are you running? Under 50, I'd say you're fine. I can get up to 60 or so with my twins and mine hold....except for that one time. At least they're easy to install. I think BD advertises that they're supposed to be good for 70psi....."not so fast my friend"....I don't buy that at this point, especially since I rarely get above 50. I think it was a little above 50 when it popped. TST was only on 1 or 2, can't remember.

When have you seen ours come apart? We just came out with these kits, before release we tested to 120 psi, with no problems. The ones at PDR are Silicone as well. Do not know about the ones from B-D. We offer full warranty on ours.

Don't give up on the BD boots.
I swapped out the stock boots to the BD ones when the twins went on. The BD boots and many others come with spring-loaded clamps but no instructions on how tight to crank the springs down. I had assumed the purpose of the spring was to keep a constant pressure on the boot but I was wrong. It sounded like a ¼ stick of dynamite going off when the boot let go at around 50 psi. I then experimented with a torque wrench and found the spring will just stack tight at about 25 inch pounds. I increased the torque to 35 inch pounds and drove around making about 50 psi of boost and found the BD boot had started to slip out from under the clamp. The final solution for me was to get rid of the springs and retrofit an aluminum spacer. The springs only seem to make it harder to take a clamp on or off. After the spring delete, I greased and torqued the boots to 100 inch pounds. This solved my problems with the boots.

so if the bd's blow and they won't warranty them if you accidentally install their funky clamps wrong because they don't supply instructions then i won't and i can only suggest nobody else buys them. anyway that's what i got from all this.
